Permit use of Preferences tab

This policy setting allows you to permit or prohibit use of the Preferences tab. When prohibited the Preferences tab does not appear when you view a preference extension in the Group Policy Management Editor window of the GPMC. The Extended and Standard tabs are unaffected and you can still create and manage preference items. If you enable this policy setting you permit use of the Preferences tab. Enabling this policy setting does not override policy settings that restrict the use of preference extensions. If you disable this policy setting you prohibit use of the Preferences tab. If you do not configure this policy setting you permit use of the Preferences tab.
